Hey guys.

One of the machines I am working with have problems with the switch user feature. When I go to the side bar of gnome desktop to switch the user and click the botton, nothing happens. I tried to run gdmflexiserver in the command line and the following error occurs:

Code:
** (gdmflexiserver:22368): WARNING **: Unable to create transient display: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.DisplayManager was not provided by any .service files
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.DisplayManager was not provided by any .service files
I haven't figured out how to fix it.

Any ideas ?

Thank you !
